Overview
The SC628AFJ is a piezoelectric audio indicator manufactured by Mallory Sonalert Products Inc. It operates on a voltage range of 6 to 28 VDC and draws a supply current between 2 and 8 mA. The device produces a continuous tone at a frequency of approximately 1900 Hz with a sound pressure level of 55 dB at 7.5 V measured at a distance of 61 cm. It features an internally driven driver circuitry designed for direct panel mounting. The unit utilizes screw terminals or quick connect tabs (0.250 inch / 6.35 mm) for electrical connection. The physical dimensions include a diameter of 1.692 inches (42.98 mm).
Feature Summary
- Piezoelectric construction for reliable audio signaling.
- Internally driven circuitry simplifies integration.
- Flexible terminal options including screw and quick connect tabs.
Applications
- Industrial equipment status indication.

- Consumer electronics fault alerts.
Procurement Notes
Verify the specific suffix requirements against the official Mallory Sonalert datasheet to ensure correct terminal type and acoustic output specifications. Confirm that the operating voltage and current ratings align with the target system design before procurement. Cross-reference the part number with authorized distributors to validate authenticity and availability.
Selection Notes
Select this component when a compact, internally driven piezoelectric buzzer is required for panel mounting applications. Ensure the available space accommodates the 1.692-inch diameter. Verify that the 55 dB sound level meets the environmental noise requirements of the installation site. Check compatibility with the existing control voltage range of 6-28 VDC.
Part Context
The SC628 series represents a foundational line of electronic sound alarms introduced by Mallory Sonalert in the early 1960s. This model continues the legacy of robust industrial audio indicators. It belongs to the broader category of piezoelectric buzzers designed for high reliability in various warning and signaling roles across multiple sectors.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Mallory Sonalert technical support for equivalent alternatives if this specific configuration is unavailable.
